City, 'in thecounty of Washington and State. ,of Tennessee,have inventedicertain new and useful Improvements in Combined Stopcocksand Drain Valves, of which the following is a specification.

This inventionlrelates to a combined stop cock and drain, valve, and'seeks, as one of its principal objects, to provide a. valve which may be operated to cut oil the supply of water. to a house or thelike and simultaneously opena drain passage for draining the;v water from'the system in thehouse-so as to prevent. freezing or in order to allow of repairs to the water system of the 'housep v The invention has as a further ob ect to provide a device wherein the valvesthereof maybe readily reground, removed or re.

newed.

The invention has as a still furtherob ject toprovide a device which will be char-v acterized by structural; simplicity and-which;

in. practical use,.will prove entirely efii cient and dependable. I Other-and incidental objects will appear hereinafter.

'llii the dI'ELWIDgSZ. I Figure 1 .is a vertical sectional view through -.my improved stop "cock and drain valve.

Figure 2 is a top plan view of the device, Figure 3 is a detail sectional view on the line 33 of Figure 1,

' Figure 4 is a detail perspective view of the J stopvalve of the device, and- Figure" 5 is a fragmentary sectional view showing the manner in which'the spindle and valve stem of the devicemay be connected for regrinding -the valves.-

In carrying the invention into effect, ll employ a shell having an -inlet passage 10, an outlet passage 11 and'a drain passage 12'depending from the bottom wall of the shell. Formed'in said bottom wall axially of the'port 16 is a beveled valve seat 17.

,Rising from the shell in concentric relation to the axis of the ports 13 and 16, is an annular'z flange 18, and sustained by the flange is,a bonnet 19 provided near its lower end with an apron 2O fitting in said flange. -The apron is formed with an annular lip 2-1 resting upon the upper end edge of said flange and threaded upon the flange is a nut 22 engaging over said lip clampmg the 'bonnet in position closing the: shell at its upper side. At its upper end, the bonnet 19 is preferablyprovided with a gland 23 and extending through said gland is a spindle 2& having threaded engagement with the honnet, as indicated at 25,.the pitch of said threads being relatively steep so that the valve heads carried by the spindle, as will be later described, may be. quickly opened or closed. vFixed to the upper end of the spindle is a hand wheel 26 and formed on 'an integral stop valve head 31'beveled toengagethe seat 17. Rising from said valve head is an annular boss 32 in which i provided a groove 33 and opening through one side of the valve head and through said boss is a recess or seat 34 removably accommo- "dating the flange 27 of the spindle 24, the fian e 28 of said spindle being disposed to "over ie the boss 32. .The'fianges 27 and 28 will thus cooperate with the boss '32 for rotatably connecting the spindle with the valve stem, and threaded upon the boss 32 to surround the flange 28 is a nut 35 overhanging-said flange for holding the valve centered with respect to the spindle. Fixed upon the lower end of the stem 30 isa drain valve 36 beveled to cooperate with the seat 14; and detachably connecting said valve of thepassage 12 is a drain port 13 at the. head with the stem is a'nut 37. Thus, when lower end of which is a beveled valve seat 14,-and, traversing the shell .Inedially thereof is adiaphragml having a port 16 for establishing communication between the inlet and outlet passages of the shell.:', The

port 16 registers with the port "13,the two ports being preferably of like diameter, and formed on. the diaphragm at the: upper end shell. On the other-hand, when thespindle 24 is operated to open the valve 31, the valve head 36 will be coincidently closed lot so that water may flow through the shell without leakage.

It is now to be observed that by removing the bonnet 19 and detaching the valve 36, the spindle 24 with the stem 30 may be removed upwardly from the shell so that the valves may be'easily renewed. 4 Furthermore, it is to be noted in this connection, that since the ports 13 and 16 are of like diameter, said ports may be readily formed at one operation and in order that the valves may be ground I provide, as shown in Figure 5, a pin 38. This pin is insertable through the, opening 29 of the spindle 24 to engage in the groove 33 of the boss 32 upon the valve 31 locking the valve to the spindle. Accordingly, the spindle may then be turned for rotating either the valve 31 or the valve 36 against the seat therefor and grinding the valves. After the grinding operation is completed, the pin 38 is, of course, removed.

mama? Having-thus described the invention, what is claimed as new is:

A valve including a shell containing a port, a spindle extending into the shell axially of said port and provided at its lower end with spaced annular flanges, and a valve head controlling the flow through said port, said valve head being provided With a recess opening through its edge and with a boss on its upperside, the recess accommodating the lower flange on the spindle and the upper flange on the spindle resting on the boss, a cap having threaded engagement with said boss and surrounding the same, and an annular collar on said cap engaging the top face of said upper flange, thereby retaining the valve head upon said spindle and centering the same.

In testimony whereofl affix my signa ture.
